Recommended USB, Ethernet, and RS-485/422 to RS-232 conversion products
Interface Conversion Products
USB - Although RS-232 is a very common serial interface standard in the industrial electronics world, many computers are now being manufactured without these familiar standard ports. However, there are many USB to RS-232 conversion products available, some at very low prices.One inexpensive converter using the FTDI UC232R chip is the DLP Design DLP-UC232R-10 (10 CM with jackpost), which is offered by a number of distributors. The DLP Design web site is www.dlpdesign.com. It is currently available from Mouser Electronics, www.mouser.com, part number 895-UC232R-10.
Another inexpensive converter using the FTDI chip is the USBGear USBG-RS232-F12 (12 inch with jackpost). The USBGear web site is www.usbgear.com.
One convertor based on the Prolific chip set that we have found at very low prices is the Sabrent Model SBT-USC1M (1 foot with jackpost), SBT-USC1K (1 foot with thumbscrew), SBT-USC6M (6 foot with jackpost), and SBT-USC6K (6 foot with thumbscrew), which are offered by many distributors. Sabrent's web site is www.sabrent.com.
Ethernet - Network connectivity for many hardware devices has also become popular, and many ethernet to RS-232 conversion products are available too.
RS485/422 - And for industrial control situations that use RS-422 or RS-485, converters to RS-232 are available.
As an added benefit some of these converters provide multiple serial ports to enable a number of devices to be connected to their own serial port.
